The Cordyceps species has been a good source of compounds with anticancer and anti-inflammatory activities. Recently, we reported a novel compound (4-isopropyl-2,6-bis(1-phenylethyl)phenol, KTH-13) with anticancer activity isolated from Cordyceps bassiana and created several derivatives to increase
A series of 4-(methylsulfonyl)aniline derivatives were synthesized in order to obtain new compounds as a potential anti-inflammatory agents with expected selectivity against COX-2 enzyme. In vivo acute anti-inflammatory activity of the final compounds 11-14 was evaluated in rat using an egg-white
TNF-alpha is a cytokine with a wide spectrum of proinflammatory activities. Nasal polyps (NP), which occur in association with allergic rhinitis and asthma, are characterized by a marked infiltration of activated eosinophils, epithelial damage, and varying degrees of stromal fibrosis. By using
Novel ethynylphenyl carbonates and carbamates containing carbon- and silicon-based choline mimics were synthesized from their respective phenol and aniline precursors and screened for anticholinesterase and anti-inflammatory activities. All molecules were micromolar inhibitors of
A convenient, oxidant-free protocol was developed for the ortho trifluoromethylation of aniline via picolinamide assisted Fe-promoted C-H functionalization under ultraviolet irradiation. In this transformation acetone essentially acted as both a solvent to dissolve reactants and a low-cost radical
Aniline exposure causes toxicity to the spleen, which leads to a variety of sarcomas, and fibrosis appears to be an important preneoplastic lesion. However, early molecular mechanisms in aniline-induced toxicity to the spleen are not known. Previously, we have shown that aniline exposure results in
Aniline exposure leads to neuron and spleen toxicity specifically and makes diverse neurological effects and sarcoma that is defined by splenomegaly, hyperplasia, and fibrosis and tumors formation at the end. However, the molecular mechanism(s) of aniline-induced spleen toxicity is not understood
6-Methoxy-1-methyl-2,3-diphenyl indol-5-carboxaldehyde (2) was demethylated to give the 6-hydroxy derivative (3) which was cyclized to the pyrano[3,2-f]indole derivatives (4a-d) by the action of ethyl acetoacetate, diethyl malonate, malononitrile, ethyl cyanoacetate. When 4c was boiled in acetic
Treatment of 2-bromoacetylbenzofuran (2) with pyridine afforded its corresponding pyridinium bromide 3. The latter salt reacted with some activated alkenes and acetylenes to give the corresponding indolizine derivatives. Treatment of the salt 3 with benzylidenemalononitriles 9 afforded
Experimental granuloma pouches were induced in the dorsum of Sprague-Dawley rats by the subcutaneous injection of either carrageenin or agar. In the former inflammation model, the hepatic activities of aminopyrine N-demethylase and aniline hydroxylase and the contents of cytochromes P-450 and b5
A novel structural class of p38 mitogen-activated protein (MAP) kinase inhibitors consisting of substituted 4-(phenylamino)-pyrrolo[2,1- f][1,2,4]triazines has been discovered. An initial subdeck screen revealed that the oxindole-pyrrolo[2,1- f][1,2,4]triazine lead 2a displayed potent enzyme
A new structural class of triaminotriazine aniline amides possessing potent p38 enzyme activity has been discovered. The initial hit (compound 1a) was identified through screening the Pharmacopeia ECLiPS compound collection. SAR modification led to the identification of a short acting
Carrageenan-induced inflammation and exposure to endotoxin considerably decreased the content of cytochrome P-450 and activities of ethylmorphine N-demethylase and meperidine N-demethylase, but did not decrease the activities of aniline hydroxylase or NADPH-cytochrome c reductase, compared with the
It has been documented that cytokines can induce the formation of reactive oxygen species (ROS) in the liver, and that an inflammatory reaction can locally increase the production of ROS, but it remains unknown whether in vivo a subcutaneous (s.c.) inflammatory reaction can induce the formation of
Hypochlorous acid (HOCl) is a chemically reactive oxidant and a potent microbicidal agent that is synthesized in phagosomes of inflammatory neutrophils and released into extracellular spaces. Besides reducing pathogenicity by reacting with phagocytized infectious agents, HOCl may damage tissues and
